DeepSeek V4 Report Signals R&D Workforce Changes

The DeepSeek V4 technical report has garnered attention due to a notable staffing shift within its research and development team. Out of nearly 300 contributors, 10 have been marked as departed, with at least five core members leaving since the latter half of 2025. These departures span critical AI areas such as base models, reasoning capabilities, OCR, and multimodal integration.

The implications of this workforce change are significant, as it may disrupt ongoing AI projects that rely on a cohesive R&D team. This shift raises concerns about maintaining the pace of innovation within national AI initiatives, potentially leading to increased reliance on foreign expertise if internal capabilities decline.
